// Helper to write a structure to the target

// Arguments:
//    T - type of structure to read.
//    pRemotePtr - remote pointer into target (dest).
//    pLocalBuffer - local buffer to write (Src). 
//
// Return Value:
//    Throws on error.
//
// Notes:
//    This just does a raw Byte copy into the Target, but does not do any Marshalling. 
//    This fails if any part of the buffer can't be written.
